Definitions

  • the invention refers to an orderly packing for a column as well as to a mass transfer column with such a packing.
  • the packing is composed, for example, of layers of sheets folded in the form of waves or zigzags.
  • the sheets consist of a foil-like material (e.g., of thin sheetmetal or fabric); the edges of the folds or the crests exhibit a direction inclined to the axis of the column, the angle included with the axis amounting, for example, to 45° or 30°.
  • the layers formed by the sheets are aligned in parallel with the axis; they are arranged alternately as regards the slope of the edges of the folds, so that open channels running obliquely and crossing one another result.
  • the packing is composed of sections which differ in the orientation of the layering. Between adjacent sections the orientation changes each time through 90°.
  • One individual section of packing of the mass transfer column may consist of a cohesive insert element; it may--especially in the case of a large diameter of the column--also be composed of a number of segments. In that case the packing often also exhibits in the interior, parting planes which run transversely to the layers; that is, junctions between adjacent segments. These parting planes interrupt the channels and exercise an edge effect because of which edge-seeking liquid also arises at the junctions.
  • FIG. 1 is a detail of a packing in perspective (without redirector elements);
  • FIG. 2 is a first embodiment of the redirector element of the packing in accordance with invention
  • FIG. 3 is a cross-section through an edge region of a column having redirector elements according to FIG. 2;
  • FIG. 4 is one part of a cross-section of a column with redirector elements at junctions between packing segments
  • FIG. 5 is a corrugated packing sheet with a groove-like recess
  • FIG. 6 is one edge of a packing which is produced through folding the sheet shown in FIG. 5;
  • FIG. 7 is one part of a cross-section of a column with a packing which is produced through multiple folding--corresponding with FIG. 6;
  • FIG. 8 is one edge of a packing with zigzag lobes as redirector elements.
  • FIG. 9 is one edge of a packing with redirector elements in the form of wire.
  • FIG. 1 The detail from a packing in FIG. 1 consists of the corrugated sheets 1 and 2 which touch at the points 12.
  • a trickling film 14 is flowing down the sheet 1 and flows on down the vertical edge 13 in the form of an edge-seeking liquid 15.
  • the sheet 1 forms the layer 10 indicated in dash dot line; the arrow 11 specifies the direction into which the trickling film is steered. If means are present which take care of a transfer of the edge-seeking liquid 15 onto the adjacent sheet 2, the transferred liquid 24 is steered by the layer 20 away from the edge 23 back into the interior of the packing (arrow 21).
  • the redirector element 3 in the form of a strip as shown in FIG. 2 consists of a corrugated foil-like material. It is made angular: the two arms 31 and 32 include a right angle at the vertical line 33. The arm 31 is in contact with the edge of the packing layer 10 carrying the edge-seeking liquid. The arm 32 points in the direction of the plane of the layer 20. A recess 22 is provided in this layer 20 for the arm 32. In the present embodiment the two arms are connected by bridgelike connector pieces 30 which form a liquid-conducting bridging-over. This redirector element 3 may be produced in a way corresponding with that explained later on in connection with FIGS. 5 and 6.
  • the charging speed was about 60 m/h (m 3 /m 2 h).
  • redirector element An important effect of the redirector element is achieved if the redirector elements are given a relatively fine profile: wavelength about 1 mm, depth of the waves about 0.5 mm.
  • wavelength about 1 mm
  • depth of the waves about 0.5 mm.
  • any value is possible which is greater than 0° and less than about 60°; preferably an angle less than 45° is chosen.
  • FIG. 3 shows an arrangement of layers 10, 20 in the packing, with associated redirector elements 3 at the column wall 9.
  • the redirector element 3 may be pressed against the edge 13 of the layer 10.
  • the redirector elements 3 may also be fastened to the packing by means of welded, screwed or riveted connections.
  • FIG. 4 shows in addition those elements 3 which lie at junctions 90 between segments of the packing in the interior of the packing.
  • the arm 31 is a little shorter than the width of the layer 10. Then for a flow of gas moving between the wall 9 of the column and the packing, essentially no obstruction exists in respect of a possible flowing back into the interior of the packing.
  • FIG. 5 a detail of a corrugated foil is shown which is sub-divided by a groovelike recess 40 into two parts 1' and 2'.
  • the two parts are connected at the points 4 like a bridge.
  • the two-layered structure of FIG. 6 is obtained (or matching the redirector element 3 shown in FIG. 2). It is folded through 180° so that the two parts 1' and 2' touch at the points 12. (In the case of the corresponding production of the redirector element 3 it is obviously folded through merely 90°).
  • the redirector elements are formed in the shape of connections 4 which produce between the edges 13' and 23' of the sheets 1' and 2'; respectively, solid bridgings-over.
  • the edge-seeking liquid 15 of the trickling film 14 is guided back into the packing again by these redirector elements 4 (arrow 24).
  • a plurality of pieces of sheet may also be folded together into a multi-layered packing segment. This is illustrated with the aid of FIG. 7.
  • the arcs 4' (at the column wall 9) and 4" (at a junction 90) symbolize redirector elements 4 in accordance with FIG. 6.
  • FIG. 8 shows as a detail the edge region of a pair of sheets 1, 2 at which the redirector elements at the edge of the layer 10 which is carrying the edge-seeking liquid 15 are made in the form of zigzag lobes 5.
  • These lobes 5 result from cutting obliquely into the edge 13 of the sheet 1 (cut edge 13a) and folding back the piece identified by a curved bracket 51 about the line 50.
  • recesses 25 are provided for the zigzag lobes 5 so that the edge-seeking liquid 25 may pass over into the neighboring layer 20 (arrow 24) unimpeded.
  • the redirector elements consist of pieces of wire 6. These redirector elements 6 in the form of wire exhibit on the one hand an end in the form of a hook by which they may be suspended in holes 16 in the sheet 1; on the other hand they are shaped in such a way that they touch (point 136) the edge 13 of the sheet. At the edge 23 of the sheet 2 recesses 26 in the form of a groove are provided for the bottom ends of the pieces of wire 6. At the point 136 the edge-seeking liquid 15 from the layer 10 is guided round towards and into the associated neighboring layer 20 (arrows 25, 24). In the event that the capacity of return of the pieces of wire 6 is too low, instead of one single piece of wire per wavelength two or more may also be provided.
